Position polarity
The polarity of the position data can be inverted according to the application. An
increasing actual position value indicates clockwise rotation (looking at the motor
shaft).

The “Position
data
weighting method" figure below shows the structure with which
the acceleration is scaled using the S
ERCOS
wizard. A distinction must be made
between linear (translational) and rotary weighting within this context.
